Background

VOCs are acronyms for volatile organic compounds (volatile organic compounds). VOCs in the general sense are commanding organic matters; but the definition in the environmental protection sense refers to an active class of volatile organic compounds, namely, volatile organic compounds which can cause harm.

VOCs, i.e., volatile organic compounds, have a great impact on human health. When the VOC in a room reaches a certain concentration, people can feel headache, nausea, vomiting, hypodynamia and the like in a short time, and can be convulsion and coma in severe cases, and the liver, the kidney, the brain and the nervous system of people can be injured, so that serious consequences such as hypomnesis are caused.

Existing methods of VOC treatment include:

1. active adsorption process

In the organic waste gas treatment process, adsorption is one of the methods with good treatment effect and wider use, the adsorbent activated carbon passes through an adsorption system, the VOC concentration can be greatly reduced, the waste gas reaches the standard and is discharged, the adsorption is desorbed through air stripping after adsorption, but the adsorption effect is greatly reduced after the activated carbon is affected with damp, the adsorbed activated carbon becomes secondary harmful waste, the replacement of the activated carbon becomes high-cost consumable materials for enterprises, the subsequent recovery and treatment also need to be completed through professional mechanisms, and the use cost is very high.

2. Induced air high-altitude discharge method

The method is one of the most convenient methods used by common enterprises in the post of paint filling, sanding and the like, and has the advantages of low cost, easy operation and obvious effect. However, the high-altitude discharge is only pollution transfer, the pollution problem is not really solved, and the power and the air inlet installation height of the induced draft fan directly influence the induced draft effect.

3. Combustion treatment process

The VOC is organic volatile substance, is easy to burn, can be treated by normal temperature or catalytic oxidation combustion, and the gas is introduced into a boiler or an incinerator for combustion through an induced air pipeline, so that the method is complete in treatment, and basically can convert the VOC into CO₂、H₂And O. However, the high-temperature organic gas is still subject to safety demonstration, and the energy consumption in the continuous combustion process is very high, so that the energy consumption cannot be saved simultaneouslyCan reduce the emission.
